The sound comes from Tokyo Ghoul:re Season 2 Episode 1, from the pre-air version circulated before broadcast, where a character repeats the threat in a frenzied outburst. Tokyo Ghoul, adapted from Sui Ishida's manga, follows Ken Kaneki in a world of ghouls and investigators, and its darker scenes produced several widely clipped lines. Fans isolated this shouting moment for soundboards and edits because it needs no context to read as pure rage. It remains popular in anime communities for villain, horror and meltdown posts where a normal reaction would feel too weak.
